Trends of Submarine Cable TechnologyTrends of Submarine Cable Technology
Development of 10Gbps/ big bandwidth transmission technology
- Commercializing 128DWDM at Trans-Pacific(9,000Km) is
possible within 2004
- Under development to apply 40Gbps/ at Trans-Pacific
Migration to Wavelength access
- Optimizing cable network to reduce the cost
- Adopting NG-SDH platform, such as MSPP

Future Plan
Next cable project
- High demand toward America
(Sharp increase of High speed Internet in Asia region)
- Under review to participate in new project
Outlook
- Unavoidableness of postponement
- Decreasing demand by World IT economic slump
(except Korea, China, Taiwan, etc.)
